flex returns: error: identifier "yy_current_buffer" is undefined

- Some lex code that used to work ok on RHEL 5, now errors out on RHEL 6 with the following message:
foo.fl(101): error: identifier "yy_current_buffer" is undefined
tmpBuff = yy_current_buffer;
- We notice that
yy_current_bufferdoes not exist any longer in RHEL 6.
